The technical solutions of the present application are described below in combination with specific embodiments.

FIG. 2 is a schematic diagram of an embodiment of a communication processing method according to an embodiment of the present application. Referring to Figure 2, communication processing methods include:

S201. The network device acquires TRS configuration information of at least one cell.

The terminal device is in the first cell, and the at least one cell is a neighbor cell of the first cell. The TRS configuration information of the at least one cell may be understood as the TRS configuration information of the at least one cell configured for the terminal device.

In some embodiments, the at least one cell and the first cell are cells in the positioning area where the terminal device is located, and the at least one cell may include other part or all of the cells in the positioning area except the first cell. That is to say, all other cells except the first cell in the positioning area may be called neighbor cells of the first cell.

For example, as shown in FIG. 4, in the user-centric positioning area (user-centric positioning area, UCPA) where the terminal device is located, the terminal device accesses the cell of gNB1 at time 1. At least one cell may include TRS configuration information of cells of gNBs other than gNB1 in the UCPA area. For example, the at least one cell may include a cell of gNB2, a cell of gNB3, a cell of gNB4, and the like.

In some implementation manners, the TRS configuration information of the at least one cell includes an identifier of the at least one cell and TRS resources respectively configured by the at least one cell for the terminal device.

The identifier of the at least one cell is used to identify the TRS configuration information of which cell the TRS configuration information is. The TRS resource of the at least one cell is used for the terminal device to receive the TRS of the at least one cell. The TRS of the at least one cell is used by the terminal device to perform time-frequency tracking with the at least one cell, so as to implement time-frequency synchronization with the at least one cell. For example, the TRS of the at least one cell is a channel state information reference signal (channel state information reference signal, CSI-RS), and the CSI-RS is used for time-frequency tracking by a terminal device.

For example, the TRS configuration information of the at least one cell includes the TRS configuration information of the cell of gNB2. The TRS resource is used for the terminal equipment to receive the TRS from the gNB2, and perform time-frequency tracking through the TRS of the gNB2, so as to realize time-frequency synchronization with the cell of the gNB2.

It should be noted that the above TRS is just an example, and the name of the TRS is not limited in this application.

Optionally, the network device may be a positioning device or a first access network device. The first access network device is the serving base station of the terminal device. The positioning device may be an LMF.

For the implementation method in which the network device is a positioning device, please refer to the embodiment shown in Figure 3 below to introduce the process of the positioning device obtaining the TRS configuration information of the at least one cell; for the implementation method in which the network device is the first access network device For details, please refer to the embodiment shown in FIG. 6 below to introduce the process for the first access network device to obtain the TRS configuration information of the at least one cell, which will not be repeated here.

S202. The network device sends TRS configuration information of at least one cell to the terminal device. Correspondingly, the terminal device receives TRS configuration information of at least one cell from the network device.

In some implementation manners, the network device is a positioning device, and the positioning device sends a provide assistant data (provide assistant data) message to the terminal device, where the provide assistant data message includes TRS configuration information of the at least one cell.

Specifically, the positioning device may send the TRS configuration information of the at least one cell to the terminal device in the form of providing an auxiliary information message through long term evolution positioning protocol (long term evolution positioning protocol, LPP) signaling.

For example, as shown in FIG. 4, the network device is an LMF, and the terminal device accesses the cell of gNB1. The LMF sends a provision assistance information message to the terminal device, and the provision assistance information message includes: TRS configuration information of the cell of gNB2, TRS configuration information of the cell of gNB3, and TRS configuration information of the cell of gNB4.

In some implementation manners, the network device is a first access network device, and the first access network device sends an RRC message to the terminal device, where the RRC message includes TRS configuration information of the at least one cell.

For example, as shown in FIG. 7, the terminal device accesses the cell of gNB1, and the network device is gNB1. gNB1 sends an RRC message to the terminal device, and the RRC message includes: TRS configuration information of the cell of gNB4, TRS configuration information of the cell of gNB5, and TRS configuration information of the cell of gNB6.

S203. When the terminal device reselects from the first cell to the second cell, and the TRS configuration information of at least one cell includes the TRS configuration information of the second cell, the terminal device receives the TRS based on the TRS configuration information of the second cell.

Specifically, the second cell is the cell of the second access network device, and the terminal device reselects from the first cell to the second cell, and the terminal device can determine whether the TRS configuration information of the at least one cell includes TRS configuration information of the second cell. If the TRS configuration information of the at least one cell includes TRS configuration information of the second cell, the terminal device may receive the TRS from the second access network device based on the TRS configuration information of the second cell.

It should be noted that if the terminal device does not reselect to the second cell, and the TRS configuration information of at least one cell includes the TRS configuration information of the second cell, the TRS configuration information of the second access network device in the second cell The TRS of the second cell will still be sent on the configured TRS resources.

For example, as shown in FIG. 4 , the terminal device accesses the cell of gNB1 at time 1, and the terminal device reselects to the cell of gNB2 at time 2. If the terminal device acquires the TRS configuration information of the gNB2 cell in the above S202, the terminal device may receive the TRS2 from the gNB2 based on the TRS configuration information of the gNB2 cell.

Optionally, the embodiment shown in FIG. 2 further includes steps S204 and S205. Step S204 and step S205 may be performed after step S203.

S204. The terminal device performs time-frequency tracking based on the TRS of the second cell.

For example, the terminal device accesses the cell of gNB1 at time 1, and the terminal device reselects to the cell of gNB2 at time 2. The terminal device may receive the TRS2 from the gNB2 based on the TRS configuration information of the cell of the gNB2, and the terminal device performs time-frequency tracking based on the TRS2, so as to realize time-frequency synchronization with the cell of the gNB2.

S205. The terminal device sends the SRS. The SRS is used to locate the terminal equipment.

Specifically, the second cell is the cell of the second access network device, and after the terminal device performs time-frequency tracking through the TRS of the second cell to achieve time-frequency synchronization with the second cell, the terminal device sends an SRS to the second access network device, The second access network device measures the SRS to determine the location of the terminal device. For example, as shown in Figure 5, the second cell is the cell of gNB2. After the terminal device switches from deep sleep (deep sleep) mode to micro sleep (micro sleep) mode, the terminal device receives TRS configuration information based on the cell of gNB2 from gNB2 TRS2, and perform time-frequency tracking through TRS2 to achieve cell time-frequency synchronization with gNB2. The terminal device is in the micro-sleep mode until the moment when the SRS is sent. After the terminal device sends the SRS, the terminal device can enter the deep sleep mode.

For example, as shown in FIG. 4 and FIG. 5 , the TRS configuration information of the at least one cell includes: TRS configuration information of the cell of gNB2, TRS configuration information of the cell of gNB3, and TRS configuration information of the cell of gNB4. The terminal device accesses the cell of gNB1 at time 1, the terminal device receives TRS1 from gNB1, and realizes time-frequency synchronization with gNB1 through TRS1. The terminal device is in the micro-sleep mode until the moment when the SRS is sent, and the terminal device sends the SRS so that the gNB1 can locate the terminal device by measuring the SRS. After the terminal device finishes sending the SRS, the terminal device may enter a deep sleep mode. The terminal device reselects from the cell of gNB1 to the cell of gNB2 at time 2. The terminal device receives the TRS2 of gNB2 based on the TRS configuration information of the cell of gNB2, and implements time-frequency synchronization with gNB2 through TRS2. The terminal device is in the micro-sleep mode until the moment when the SRS is sent, and the terminal device sends the SRS so that the gNB2 can locate the terminal device by measuring the SRS. After the terminal device finishes sending the SRS, the terminal device may enter a deep sleep mode. The process of the terminal device reselecting to the cell of gNB3 at time 3 and the process of reselecting the terminal device to the cell of gNB4 at time 4 is also similar, and details will not be described one by one. It can be seen that, through the technical solution of the present application, the neighbor cell pre-configures the TRS configuration information of the neighbor cell for the terminal device, and sends it to the network device. The network device sends the TRS configuration information of the neighbor cell to the terminal device. After the terminal device reselects to the neighbor cell, the terminal device can receive the TRS directly based on the TRS configuration information of the neighbor cell. Therefore, after reselecting to a neighbor cell, the terminal device does not need to request the TRS configuration information of the neighbor cell from the neighbor cell. Therefore, the terminal device does not need to switch from the idle state or the inactive state to the connected state, thereby reducing the power consumption of the terminal device and improving the battery life of the terminal device.

Optionally, the above embodiment shown in FIG. 2 further includes step S206 to step S208. Step S206 to step S208 may be performed after step S202.

S206. When the terminal device reselects from the first cell to the second cell, and the TRS configuration information of the at least one cell does not include the TRS configuration information of the second cell, the terminal device receives the SSB of the second cell.

Specifically, the terminal device may determine whether the TRS configuration information of the at least one cell includes the TRS configuration information of the second cell through the identifier of the second cell. If the TRS configuration information of the at least one cell does not include the TRS configuration information of the second cell and the terminal device reselects to the second cell, the terminal device can receive the SSB of the second cell, so that when the terminal device and the second cell realize frequency synchronization.

Some possible situations in which the TRS configuration information of the at least one cell does not include the TRS configuration information of the second cell are introduced below.

Case 1. The network device requests the neighbor cell to configure the TRS configuration information of the second cell for the terminal device, but the neighbor cell refuses to configure the TRS configuration information of the second cell for the terminal device. For example, the neighbor cell has no free TRS resources to configure, and the neighbor cell rejects the network device's request.

In case 2, the network device is the serving base station of the terminal device, and no Xn interface connection is established between the serving base station and the base station of the neighboring cell. The serving base station cannot send a TRS configuration request to the base station of the neighbor cell, so that the serving base station cannot provide the TRS configuration information of the second cell to the terminal device.

S207. The terminal device performs time-frequency tracking based on the SSB of the second cell.

For example, as shown in FIG. 7 , the terminal device reselects to the cell of gNB5 at time 3, and the TRS configuration information of the at least one cell does not include the TRS configuration information of the cell of gNB5. The terminal device can perform time-frequency tracking based on the SSB5 of the gNB5 cell, so as to realize time-frequency synchronization with the gNB5.

S208. The terminal device sends an SRS.

Specifically, the second cell is the cell of the second access network device, and after the terminal device performs time-frequency tracking through the SSB of the second cell to achieve time-frequency synchronization with the second cell, the terminal device sends an SRS to the second access network device, The second access network device measures the SRS to determine the location of the terminal device. For example, as shown in Figure 7 and Figure 8, the second cell is the cell of gNB5, after the terminal device switches from deep sleep (deep sleep) mode to micro sleep (micro sleep) mode, the terminal device receives SSB5 from gNB5, and passes SSB5 performs time-frequency tracking to achieve cell time-frequency synchronization with gNB5. The terminal device is in the micro-sleep mode until the moment when the SRS is sent. After the terminal device sends the SRS, the terminal device can enter the deep sleep mode.

In the above technical solution, the TRS configuration information of the second cell may be configured with reference to the SRS configuration information of the terminal device. That is, the TRS configuration information of the second cell is associated with the SRS configuration information of the terminal device. Therefore, compared with the scheme in which the terminal device realizes time-frequency synchronization through the TRS of the second cell, the terminal device waits for a shorter time to send the SRS in the micro-sleep mode, which is beneficial to Reduce power consumption of end devices. Moreover, the terminal device can realize timely time-frequency synchronization through the TRS of the second cell, so that the terminal device can send the SRS, so that the second cell can receive the SRS sent by the terminal device on the corresponding SRS resource. It is avoided that the process of sending the SRS by the terminal device is interfered with or interferes with the communication of other terminal devices due to the time-frequency deviation.

For example, as shown in FIG. 7 and FIG. 8 , the TRS configuration information of the at least one cell includes: TRS configuration information of the cell of gNB4. The terminal device accesses the cell of gNB1 at time 1, the terminal device receives TRS1 from gNB1, and realizes time-frequency synchronization with gNB1 through TRS1. The terminal device is in the micro-sleep mode until the moment when the SRS is sent, and the terminal device sends the SRS so that the gNB1 can locate the terminal device by measuring the SRS. After the terminal device finishes sending the SRS, the terminal device may enter a deep sleep mode. The terminal device reselects from the cell of gNB1 to the cell of gNB4 at time 2. The terminal device receives the TRS4 of gNB4 based on the TRS configuration information of the cell of gNB4, and realizes time-frequency synchronization with gNB4 through TRS4. The terminal device is in the micro-sleep mode until the moment when the SRS is sent, and the terminal device sends the SRS so that the gNB4 can locate the terminal device by measuring the SRS. It can be seen that the neighbor cell pre-configures the TRS configuration information of the neighbor cell for the terminal device, and sends the TRS configuration information of the neighbor cell to the network device. The network device sends the TRS configuration information of the neighbor cell to the terminal device. After the terminal device reselects to the neighbor cell, the terminal device can receive the TRS directly based on the TRS configuration information of the neighbor cell. Therefore, after reselecting to a neighbor cell, the terminal device does not need to request the TRS configuration information of the neighbor cell from the neighbor cell. So the end device does not need to switch from the idle or inactive state to the connected state. Therefore, the power consumption overhead of the terminal device is reduced, and the battery life of the terminal device is improved. Secondly, the TRS configuration information of the at least one cell may be configured by the at least one cell with reference to the SRS configuration information of the terminal device, that is, there is an association relationship between the TRS configuration information of the at least one cell and the SRS configuration information. For example, the period of the SRS resource of the terminal device is an integer multiple of the period of the TRS resource, or the time interval between the time slot or the time domain symbol where the SRS resource and the TRS resource are located is relatively small. For example, for the TRS configuration information of the cell of gNB4, the terminal device can send SRS in a short time after realizing time-frequency synchronization through TRS4, and enter the deep sleep mode after sending the SRS. Thereby reducing the time that the terminal device is in the micro-sleep mode, realizing low power consumption positioning, and improving the battery life of the terminal device.

After the terminal device finishes sending the SRS, the terminal device may enter a deep sleep mode. The terminal device reselects from the cell of gNB4 to the cell of gNB5 at time 3. The terminal device receives SSB5 from gNB5, and realizes time-frequency synchronization with gNB5 through SSB5. The terminal device is in the micro-sleep mode until the moment when the SRS is sent, and the terminal device sends the SRS so that the gNB5 can locate the terminal device by measuring the SRS. The terminal device reselects from the cell of gNB5 to the cell of gNB6 at time 3. The terminal device receives SSB6 from gNB6, and implements time-frequency synchronization with gNB6 through SSB6. The terminal device is in the micro-sleep mode until the moment when the SRS is sent, and the terminal device sends the SRS so that the gNB6 can locate the terminal device by measuring the SRS. It can be seen that, when the terminal device moves to the second cell, the TRS configuration information of the at least one cell does not include the TRS configuration information of the second cell. The terminal device can realize time-frequency synchronization through the SSB of the cell.

In this embodiment of the present application, the terminal device receives TRS configuration information from at least one cell of the network device, the terminal device is in a first cell, and the at least one cell is a neighbor cell of the first cell. When the terminal device reselects from the first cell to the second cell, and the TRS configuration information of the at least one cell includes the TRS configuration information of the second cell, the terminal device receives the TRS of the second cell based on the TRS configuration information of the second cell. It can be known from this that the terminal device first receives the TRS configuration information of the second cell from the network device. After the terminal device reselects from the first cell to the second cell, the terminal device may receive the TRS of the second cell based on the TRS configuration information of the second cell. The terminal device does not need to switch from the idle state or the inactive state to the connected state in order to obtain the TRS configuration information configured for the terminal device by the serving base station of the neighbor cell. Thereby, the power consumption overhead of the terminal equipment is reduced, and the battery life of the terminal equipment is improved.

The following describes the process of the positioning device acquiring the TRS configuration information of the second cell and the process of the positioning device sending the TRS configuration information of the second cell to the terminal device with reference to the embodiment shown in FIG. 3 .

FIG. 3 is a schematic diagram of another embodiment of a communication processing method according to an embodiment of the present application. Referring to Figure 3, communication processing methods include:

S301. The positioning device sends a first positioning information request message to the second access network device. Correspondingly, the second access network device receives the first positioning information request message from the positioning device.

The second access network device is a serving base station of the second cell, the terminal device is in the first cell, the second cell is a neighbor cell of the first cell, and the positioning device may be an LMF.

Some possible implementations of the contents included in the first location information request message are introduced below.

Implementation mode 1. The first location information request message includes first indication information, and the first indication information is used to request or instruct the second access network device to configure TRS configuration information of the second cell.

Implementation mode 2. The first positioning information request message includes the first recommended TRS configuration information, and is used for the second access network device to configure the TRS configuration information of the second cell with reference to the first recommended TRS configuration information.

Optionally, the first recommended TRS configuration information includes part or all of the TRS configuration information of the first cell, where the first cell is the cell where the terminal device is located. For example, the first recommended TRS configuration information includes the period, time slot offset, etc. of the TRS resource of the first cell.

In this implementation manner, the positioning device may acquire TRS configuration information of the first cell. A possible implementation manner for the positioning device to obtain the TRS configuration information of the first cell is introduced below in conjunction with step S301a and step S301b.

Optionally, the embodiment shown in FIG. 3 further includes step S301a and step S301b, and step S301a and step S301b may be performed before step S301.

S301a. The positioning device sends a second positioning information request message to the first access network device. The second location information request message includes third indication information. Correspondingly, the first access network device receives the second positioning information request message from the positioning device.

Wherein, the first access network device is a serving base station of the first cell, and the terminal device is located in the first cell. The third indication information is used to instruct the first access network device to configure the TRS configuration information of the first cell with reference to the SRS configuration information of the terminal device.

Specifically, the positioning device may send a second positioning information request message to the first access network device through new radio positioning protocol A (new radio positioning protocol A, NRPPa) signaling.

S301b. The first access network device sends a second positioning information response message to the positioning device. The second location information response message includes TRS configuration information of the second cell. Correspondingly, the positioning device receives the second positioning information response message from the first access network device.

Specifically, after the first access network device receives the second location information request message, the first access network device may configure the TRS configuration information of the first cell with reference to the SRS configuration information of the terminal device according to the third indication information. The SRS configuration information of the terminal device is associated with the TRS configuration information of the first cell. The first access network device sends a second positioning response message to the positioning device, where the second positioning information response message includes TRS configuration information of the first cell. For example, the first access network device sends the second positioning response message to the positioning device through NRPPa signaling.

For example, as shown in Figure 4 and Figure 5, when a terminal device accesses the cell of gNB1, the terminal device receives TRS1 from gNB1 through the TRS configuration information of the cell of gNB1, and after realizing time-frequency synchronization through TRS1, the terminal device The SRS can be sent, and the terminal device enters a deep sleep mode after sending the SRS, so as to realize low-power positioning of the terminal device and reduce power consumption of the terminal device. That is to say, the first access network device configures the TRS configuration information of the first cell with reference to the SRS configuration information of the terminal device, so that the SRS resource is associated with the TRS resource, which is beneficial for the terminal device to reduce power consumption. The SRS resources of the terminal device in the positioning area are shared, that is, the SRS resources used by the terminal device in different cells in the positioning area are the same (SRS resources include the time-frequency resources used by the terminal device to send SRS, as shown in Figure 5 The example only shows that the time domain resources used by the terminal device to send SRS in different cells are the same, in fact, the frequency domain resources used by the terminal device to send SRS in different cells are also the same), so the positioning device Send the TRS configuration information of the first cell to the second access network device. It is beneficial for the second access network device to configure the TRS configuration information of the second cell associated with the SRS configuration information of the terminal device for the terminal device, thereby further reducing power consumption overhead and improving the battery life of the terminal device.

Implementation manner 3. The first positioning information request message includes SRS resource reservation information and second indication information.

Wherein, the second indication information is used to instruct the second access network device to configure the TRS resource associated with the SRS resource corresponding to the SRS resource reservation information. Optionally, the SRS resource reservation information includes configuration information of SRS resources of the terminal device. The second access network device reserves the SRS resource for the terminal device through the SRS resource reservation information.

S302. The second access network device sends a first positioning information response message to the positioning device. The first positioning information response message includes TRS configuration information of the second cell. Correspondingly, the positioning device receives the second positioning response message from the second access network device.

1. Based on the first implementation of step S301, the second access network device configures the TRS configuration information of the first cell according to the first indication information. Then, the second access network device sends a first positioning information response message to the positioning device. The first positioning information response message includes TRS configuration information of the second cell.

2. Based on the implementation manner 2 of step S301 above, the second access network device configures the TRS configuration information of the second cell with reference to the first recommended TRS configuration information.

Optionally, the first recommended TRS configuration information includes part or all of the TRS configuration information of the first cell. The second access network device configures TRS configuration information of the second cell with reference to the first recommended TRS configuration information. For example, the second access network device may use the first recommended TRS configuration information as the TRS configuration information of the second cell. In the positioning area, the SRS resources of the terminal device in different cells are shared, that is, the SRS resources used by the terminal device in different cells in the positioning area are the same. Combining the above step S301a and step S301b, it can be known that the positioning device sends the TRS configuration information of the first cell to the second access network device, which is beneficial for the second access network device to refer to the TRS configuration information of the first cell for the terminal device configuration and terminal device The TRS configuration information of the second cell associated with the SRS configuration information of the SRS configuration information, thereby further reducing power consumption overhead. The second access network device sends the first positioning information response message to the positioning device. The first positioning information response message includes TRS configuration information of the second cell.

For example, as shown in Figure 4 and Figure 5, the terminal device reselects to the cell of gNB2 at time 2, the terminal device receives TRS2 from gNB2 through the TRS configuration information of the cell of gNB2, and after realizing time-frequency synchronization through TRS2, the terminal device The SRS can be sent in a short time, and the terminal device enters a deep sleep mode after sending the SRS, so as to realize the low power consumption positioning of the terminal device and reduce the power consumption cost of the terminal device. That is to say, the second access network device configures the TRS configuration information of the second cell with reference to the TRS configuration information of the first cell, so that the SRS resource is associated with the TRS resource, which is beneficial for the terminal device to reduce power consumption.

3. Based on the implementation manner 3 of the above step S301, the second access network device configures the TRS configuration information of the second cell with reference to the SRS resource reservation information according to the second indication information.

Specifically, the SRS resource reservation information includes configuration information of the SRS resource of the terminal device. For example, the SRS resource reservation information includes the time-frequency position where the SRS resource of the terminal device is located. The second access network device reserves the SRS resource for the terminal device through the SRS resource reservation information. The second access network device may configure TRS configuration information of the second cell associated with the SRS resource according to the second indication information. Then the second access network device sends the first positioning information response message to the positioning device. The first positioning information response message includes TRS configuration information of the second cell. In order for the positioning device to send the TRS configuration information of the second cell to the terminal device. Based on the implementation manner 3, the TRS configuration information of the second cell is associated with the SRS resource corresponding to the SRS resource reservation information. It is beneficial to further reduce the power consumption overhead of the terminal equipment.

For example, as shown in Figure 4 and Figure 5, the terminal device reselects to the cell of gNB2 at time 2, the terminal device receives TRS2 from gNB2 through the TRS configuration information of the cell of gNB2, and after realizing time-frequency synchronization through TRS2, the terminal device The SRS can be sent in a short time, and the terminal device enters a deep sleep mode after sending the SRS, so as to realize the low power consumption positioning of the terminal device and reduce the power consumption cost of the terminal device. That is to say, the second access network device configures the TRS configuration information of the second cell with reference to the SRS resource reservation information, so that the SRS resource is associated with the TRS resource, which is beneficial for the terminal device to reduce power consumption.

S303. The positioning device sends a message of providing auxiliary information to the terminal device. The providing assistance information message includes TRS configuration information of the second cell. Correspondingly, the terminal device receives the message of providing auxiliary information from the positioning device.

The above-mentioned embodiment shown in FIG. 3 shows a process in which the positioning device acquires the TRS configuration information of the second cell and the positioning device sends the TRS configuration information of the second cell to the terminal device. The same applies to the process of acquiring and sending the TRS configuration information of other cells in the at least one cell, which is not limited in this application.

In the technical solution of the embodiment shown in FIG. 3 above, the positioning device instructs the second access network device to configure TRS configuration information of the second cell. The second access network device preconfigures the TRS configuration information of the second cell for the terminal device, and then the positioning device sends the TRS configuration information of the second cell to the terminal device. In this way, when the terminal device reselects to the second cell, the terminal device can directly receive the TRS of the second cell based on the TRS configuration information of the second cell. The terminal device does not need to switch from the idle state or the inactive state to the connected state in order to obtain the TRS configuration information that the serving base station of the second cell configures the terminal device with the second cell. It avoids the problem that the power consumption of the terminal equipment increases due to switching to the connected state after the terminal equipment is reselected to the second cell, thereby reducing the power consumption overhead of the terminal equipment and improving the battery life of the terminal equipment. Further, the second access network device may configure TRS configuration information of the second cell associated with the SRS configuration information of the terminal device. The terminal device enters the micro-sleep mode, and after receiving the TRS based on the TRS configuration information of the second cell and performing time-frequency synchronization, the terminal device can send the SRS in a short time. The terminal device can enter the deep sleep mode after sending the SRS. In deep-sleep mode, the end device only needs to maintain a very low clock current. Therefore, the time for the terminal device to be in the micro-sleep mode is reduced, the power consumption of the terminal device is reduced, and the battery life of the terminal device is improved.

The following describes the process of obtaining the TRS configuration information of the second cell by the first access network device and the process of sending the TRS configuration information of the second cell to the terminal device by the first access network device with reference to the embodiment shown in FIG. 6 .

FIG. 6 is a schematic diagram of another embodiment of a communication processing method according to an embodiment of the present application. Referring to Figure 6, communication processing methods include:

S601. The first access network device sends a TRS configuration request (TRS configuration request) message to the second access network device. The TRS configuration request message includes fourth indication information and second TRS recommended configuration information. Correspondingly, the second access network device receives the TRS configuration request message from the first access network.

The terminal device is in the first cell, and the first access network device is a serving base station of the first cell. The second access network device is a serving base station of the second cell, and the second cell is a neighbor cell of the first cell. The fourth indication information is used to instruct the second access network device to configure the TRS configuration information of the second cell with reference to the second TRS recommended configuration information.

Specifically, the first access network device is connected to the second access network device through an Xn interface. The first access network device may send a TRS configuration request message to the second access network device through the Xn interface. The Xn interface may be a physical interface or a logical interface. There may be a direct physical connection between the first access network device and the second access network device, and the first access network device may directly send a TRS configuration request message to the second access network device. There may also be no direct physical connection between the first access network device and the second access network device, that is, the first access network device may forward the TRS configuration request message to the second access network device through an intermediate node.

Optionally, the second TRS recommended configuration information includes part or all of the TRS configuration information of the first cell. For example, the second TRS recommended configuration information includes the period and time slot offset of the TRS resource configured in the TRS configuration information of the first cell.

S602. The second access network device sends a TRS configuration response message to the first access network device. The TRS configuration response message includes TRS configuration information of the second cell. Correspondingly, the first access network device receives the TRS configuration response message from the second access network device.

Specifically, after the second access network device receives the TRS configuration request message, the second access network device configures the TRS configuration information of the second cell with reference to the second TRS recommended configuration information according to the fourth indication information. Then, the second access network device sends a TRS configuration response message to the first access network device through the Xn interface. The TRS configuration response message includes TRS configuration information of the second cell.

For example, as shown in Figure 7, gNB1 is the first access network device, and gNB4 is the second access network device. gNB1 sends a TRS configuration request message to gNB4 through the Xn interface, and the TRS configuration request message includes fourth indication information and second TRS recommended configuration information. The gNB4 configures the TRS configuration information of the cell of the gNB4 for the terminal device with reference to the second TRS recommended configuration information according to the fourth indication information.

Optionally, the TRS configuration response message further includes fifth indication information, where the fifth indication information is used to indicate that configuration of the TRS configuration information of the second cell is completed.

Specifically, the first access network device may configure the TRS configuration information of the first cell for the terminal device with reference to the SRS configuration information of the terminal device. The SRS configuration information of the terminal device is associated with the TRS configuration information of the first cell. The SRS resources of the terminal equipment in the positioning area are shared, that is, the SRS resources used by the terminal equipment in different cells within the positioning area are the same. Therefore, when the first access network device requests the second access network device to configure the TRS configuration information of the second cell, it sends the TRS configuration information of the first cell to the second access network device. It is beneficial for the second access network device to configure the TRS configuration information of the second cell associated with the SRS configuration information of the terminal device for the terminal device by referring to the TRS configuration information of the first cell. It is beneficial for the terminal equipment to further reduce power consumption overhead.

For example, as shown in FIG. 7 and FIG. 8 , the terminal device reselects from the cell of gNB1 to the cell of gNB4 at time 2. The terminal device receives the TRS4 of gNB4 based on the TRS configuration information of the cell of gNB4, and realizes time-frequency synchronization with gNB4 through TRS4. The terminal device is in the micro-sleep mode until the moment when the SRS is sent, and the terminal device sends the SRS so that the gNB4 can locate the terminal device by measuring the SRS. After the terminal device finishes sending the SRS, the terminal device may enter a deep sleep mode. It can be seen that the second access network device configures the TRS configuration information of the second cell associated with the SRS configuration information of the terminal device for the terminal device by referring to the TRS configuration information of the second cell. Therefore, after the terminal device receives the TRS based on the TRS configuration information of the second cell and performs time-frequency synchronization, it can send the SRS in a short time. The terminal device can enter the deep sleep mode after sending the SRS. Therefore, the time for the terminal device to be in the micro-sleep mode is reduced, and the power consumption of the terminal device is reduced. Thereby improving the battery life of the terminal equipment. Moreover, through the technical solution of this application, after the terminal device reselects to a neighbor cell, the terminal device does not need to switch from the idle state or the inactive state to the connected state (for the terminal device to request the TRS configuration information of the neighbor cell from the neighbor cell), Thereby reducing the power consumption overhead of the terminal equipment.

S603. The first access network device sends an RRC message to the terminal device. The RRC message includes TRS configuration information of the second cell. Correspondingly, the terminal device receives the RRC message from the first access network device.

Optionally, the first access network device may send the TRS configuration information of the first cell and the TRS configuration information of the second cell to the terminal device through the same RRC message, or may send the TRS configuration information of the first cell to the terminal device through different RRC messages. The TRS configuration information and the TRS configuration information of the second cell are not limited in this application.

The above-mentioned embodiment shown in FIG. 6 shows a process in which the first access network device obtains the TRS configuration information of the second cell and the first access network device sends the TRS configuration information of the second cell to the terminal device. The same applies to the process of acquiring and sending the TRS configuration information of other cells in the at least one cell, which is not limited in this application.

In the technical solution of the embodiment shown in FIG. 6 above, the first access network device sends a TRS configuration request message to the second access network device through the Xn interface. The TRS configuration request message includes fourth indication information and second TRS recommended configuration information. The second access network device pre-configures the TRS configuration information of the second cell for the terminal device with reference to the second TRS recommended configuration information according to the fourth indication information. The second access network device sends a TRS configuration response message to the first access network device, where the TRS configuration response message includes TRS configuration information of the second cell. Then, the first access network device sends the TRS configuration information of the second cell to the terminal device. In this way, when the terminal device reselects to the second cell, the terminal device can directly receive the TRS of the second cell based on the TRS configuration information of the second cell. The terminal device does not need to switch from the idle state or the inactive state to the connected state, so as to obtain the TRS configuration information of the second cell configured by the serving base station of the second cell for the terminal device, thereby reducing power consumption of the terminal device. It avoids the problem that the power consumption of the terminal equipment increases due to switching to the connected state after the terminal equipment is reselected to the second cell, thereby reducing the power consumption overhead of the terminal equipment and improving the battery life of the terminal equipment. Further, the second access network device may configure TRS configuration information of the second cell associated with the SRS configuration information of the terminal device. The terminal device enters the micro-sleep mode, and after receiving the TRS based on the TRS configuration information of the second cell and performing time-frequency synchronization, the terminal device can send the SRS in a short time. After the terminal device sends the SRS, it can enter the deep sleep mode. In the deep sleep mode, the terminal device only needs to maintain an extremely low clock current. Therefore, the time for the terminal device to be in the micro-sleep mode is reduced, the power consumption of the terminal device is reduced, and the battery life of the terminal device is improved.
